fn push_inner<I: Interner>(
stack: &mut SmallVec<[<I as Interner>::GenericArg; 8]>,
parent: I::GenericArg,
)Expand description
We push GenericArgs on the stack in reverse order so as to
maintain a pre-order traversal. As of the time of this
writing, the fact that the traversal is pre-order is not
known to be significant to any code, but it seems like the
natural order one would expect (basically, the order of the
types as they are written).
